Recent Basement Waterproofing Reviews in Seattle

  • Wu Construction

    It went very well. Greg was a great guy. In the initial consultation we missed a wall that also needed a drain due to the crawl space, and his lovely crew came back and made it right. Greg was also always available to answer my many questions and made sure I was completely comfortable in the work. This is the first time I have had a dry basement as long as I have owned the house! I cant recommend highly enough

    We had a foot of water in our crawl space after the snow and 6 in. of rain from the December 2021 storms. I had called several companies to come out to take a look and give quotes. Ethan from diversified was the 3rd quote we received. Ethan explained the issue, explained what they would do to remedy it, and answered all my questions. He sent me the quote which was very resonable. BE SURE TO GET SEVERAL QUOTES. ONE COMPANY QUOTED US DOUBLE OF WHAT WE PAID DIVERSIFIED. They were able to get a team out two days later. The team was on time, professional, and did really good work. We ended up needing a sump pump due to ground water coming up. They applied a mold application and completed the work in a day. I highly recommend these guys and did my research prior to having them do the work. I am very impressed and happy we chose them

    Our experience with Wu Construction was awesome. We had water coming into our basement, gave them a call, and from consultation through installation, they were one of the most courteous and professional contractors we've dealt with. Their work is quality, prices competitive, and communication was excellent. Would recommend them to anyone with water issues

    We got a bid from Andy Construction for water-issues in our crawlspace. Of the companies that I talked to about this issue - I thought Andy provided the most objective recommendation (though it costed lesser). Other companies were recommending a sump pump. Andy recommended addressing the source of the water (downspout drainage issue). We haven't yet gotten the work completed, but would recommend Andy Construction based on the bidding process

    I have a 1906 cottage in N Seattle, with an old porous foundation. Water came into the basement for the first time in 20 years. Another contractor bid the job at $12,000 after 3 site visits and almost a month. Andy came out to the house the same day I talked to him, and estimated the same job at half that price. He followed up with questions, asked about making another visit, came out again and saw that the drainpipe was disconnected at the top of the area being flooded. 75% of the roof's water was pooling against the house. He found a ladder and fixed it and isn't charging me a dime. So, no French drain, no Delta drain, no foundation treatment, no 50' of trenching, no $$$. Andy was timely, reliable, did what he said, and knows his stuff. He was a great communicator, and I feel so so lucky to have found him

    Galen is SUPER helpful! While unfortunately it was not work that his company could do because of how our house is structured, he took the time to evaluate what the cause of the leak was and whether or not it was foundation-issues or something else. Very thorough and if we do need something more appropriate for his company will definitely call again

    The service was excellent. Enrique came in less than 24 hours from our call and about 24 hours before he was scheduled. We showed him the problem and he promptly fixed it. He sent a video to the mitigator who was then able to come out and assess other damage. He also pressure tested the pipe afterwards to demonstrate that the fix was definite. Thank you Enrique

    Allan did a kitchen remodel for us in our condo. He demo'd our old kitchen, and installed new vinyl flooring, cabinets, and countertops. A few highlights: 1) From the initial call, Allan was quick to respond with pricing, contract, scope of work, etc. We were very happy with how professional and reliable he was throughout the full project - scoping the work, assisting with material selection, to the actual remodel. 2) While onsite, I asked Allan to make other modifications to our condo that were out of scope. Allan was fair and reasonable, and we were quickly able to agree on a price for the additional work. Allan did not nickel and dime on every little adjustment, and it greatly improved the overall experience of working with Allan. 3) Allan is very customer focused. He gave insights and recommendations into materials, design choices, and solutions - and it was very helpful to have a trusted, professional opinion on different matters. He guided us with recommendations on flooring, layout changes, etc that was very helpful, and was clear in communicating the options without making me feel like he was trying to up-sell more work. I felt that Allan was truly wanting to help us create the kitchen we wanted and not pushing his own agenda. It was super helpful to have him propose different options as we weighed different factors (budget, utility, decor, etc) to make our selections. 4) The quality of work was excellent. Allan and his team are committed to doing a good job. When we pointed out areas that we were concerned about or anxious with, Allan made sure to always make any adjustments we asked for and made sure it was just to our liking. At the end of the day, we are very happy with how the project turned out. Our new kitchen looks amazing, and we would absolutely work with Allan and Mimos Remodeling again on future projects. Thank you Allan

    Better than I could have asked for. They came up with a GREAT solution to my basement leaking issues (I had a river in my basement last winter) thus far this fall not a drop. His option was faster, cheaper and more effective than the other 3 companies i had bid the job. I could not be happier!

    We've had a handful of unsatisfying contractor experiences, so we tend to be a bit skeptical but our experience with Terra Firma set a new bar for us. Highly professional from start to finish. Initial consult was thorough, and didn't add on anything we didn't ask for or need. When they were working at the house the crew was prompt, professional, left the jobsite clean each day. Final result was exactly what we were expecting. Worth the investment, don't go with the lowest bidder on your foundation, it's not worth it. Thank you Terra Firma crew

    I am extremely happy with with Wu Construction! From start to finish it has been a very pleasant experience. First, I send a frantic email after heavy rains to which I received a quick and reassuring reply - on the weekend! Next Greg came out to quote, provided a good price and was able to get the work scheduled for me on the spot for only a week later. Thanks Greg! Today the technicians arrived right on time, were very professional and did an amazing job. I kept peaking outside to see what was happening and I could tell they were executing the work with great care and attention. The quality of the work exceeded my expectations. Also it was discovered midday that more work was needed than originally thought when one of my downspouts was unearthed full of roots. I appreciate that they were able to accommodate the additional work and still complete everything in one day
